Get This Price

This is the lowest price Fostex's Mk2 flagship has ever hit. The 30-day average sat at $1916.30 and the 90-day average at $2199.66, so today's tag undercuts both by a wide margin.

For just $1465.50, down from its list price of $2899.99, this lands well below anything the TH1100RPmk2 has sold for since launch.

What You're Getting

The TH1100RPmk2 runs on Fostex's 4th-generation RP planar drivers, tuned for high-resolution playback with low distortion and snappy transient response. The open-back shell uses double-layered aluminum apertures to open up airflow, which widens the soundstage and pulls more detail out of the mix. A lightweight magnesium alloy frame trims roughly 20% of the weight versus aluminum, and the redesigned Mk2 ear pads pair a two-layer foam structure with silk-protein leather for a softer fit and a tighter acoustic seal.

Who This Is For

Best for serious headphone buyers who want a flagship planar without paying flagship money. If you are building a dedicated reference listening setup and you have a quality amp on hand. This is the class of driver you want.

Casual listeners who are happy with a mid-tier closed back can skip it, since this is a demanding, source-hungry open-back design.

Final Verdict

The TH1100RPmk2 at $1465.50 clears its own all-time low by a significant stretch, and it beats the 90-day average by more than $700. If you are in the market for a reference-grade planar. This is the price to move on.
